You are instructing new crew members in engine room safety and first aid. You use an example of "One crew member, while working in the engine room, finds another crew member lying unconscious on the deck." What would you instruct the crew do first when faced with the rescue of this crew member?

Correct Answer: Option D — Make sure they summon help immediately.

Summoning help immediately ensures that emergency medical support and back-up personnel are en route before entering a potentially hazardous space. Engine rooms often contain hidden hazards like toxic gases or live machinery; lone rescuers frequently become additional casualties without proper backup.
